The warranty on a concrete overlay is only as good as its exclusions and the people who stand behind it. An exclusion is a cause the warranty won’t pay for. On September 28, 2026, we looked up 40 overlay, resurfacing, and manufacturer listings across Oklahoma, Arkansas, Missouri, Mississippi, Tennessee, and Texas. 23 published a term in writing. 4 promised coverage with no term at all. The other 13 had no terms for us to read, or the page wouldn’t load.
Most of those 23 were a number and a line or two. The long lists of exclusions came from the firms that make overlay and moisture-control products. We put each clause in our own words, as we read it on September 28, 2026, and we leave company names out, because the point is the clause, not who wrote it. Below are the 11 clauses we’d ask about before signing. Each one comes with a question that turns it into something you can hold a contractor to.
Some exclusions are normal. Ours has them too. Our written terms leave out the slab below: cracks, movement, and moisture coming up through it. They also leave out color and matching, normal wear, upkeep, and damage by others. Repairs someone else makes before we get to look are out too, unless it was an emergency. Our longest term, lifetime, runs as long as the person who hired us still owns the property. The trouble starts when a clause names a cause nobody can test for. It’s also trouble when the firm gets to be the only judge.
Short on time? These are the weakest terms we saw:
- coverage for one failure only, like the bond or flaking (clause 1)
- a moisture exclusion with no test or number (clause 3)
- “normal use” with no written care plan (clause 4)
- a reseal rule that can end all coverage (clause 5)
- material coverage with no labor or install (clause 8)
- a short clock to report, or a fee on a denied claim (clauses 9 and 10)
What did we find in each state?
In each state, we searched the bigger cities for crews that do overlays, resurfacing, microtopping, and stamped overlays. Microtopping is a very thin overlay, often troweled on by hand. Then we read whatever each firm put out. We also read the terms of 10 firms that make overlay and moisture-control products. Crews often hand those papers to their customers.
| Where we looked | Listings checked | Published a term in writing | Promise with no term | No claim, or page failed |
|---|---|---|---|---|
| Oklahoma | 3 | 2 | 0 | 1 |
| Arkansas | 5 | 1 | 1 | 3 |
| Missouri | 5 | 1 | 2 | 2 |
| Mississippi | 7 | 1 | 1 | 5 |
| Tennessee | 5 | 4 | 0 | 1 |
| Texas | 5 | 5 | 0 | 0 |
| Overlay and moisture-control manufacturers | 10 | 9 | 0 | 1 |
| Total | 40 | 23 | 4 | 13 |
Three notes on the rows. “Published a term in writing” means at least a number of years on the page, and several of those pages listed no exclusions at all. One Missouri listing sits just across the state line in Kansas. Two of the Texas listings are floor coating firms that also sell concrete resurfacing.
1. Coverage that names only one failure
Bond failure is the main way an overlay fails. The bond is the grip between the overlay and the slab under it. So coverage for the bond is the heart of any fair overlay term. One Missouri resurfacing firm writes it about as plainly as we found. It gives a 2-year warranty against bond failure. If the overlay comes off, the firm fixes it at no charge, for both product and labor.
Other terms narrow it more. One Texas overlay crew offers a limited warranty of about five years on homes and one year on commercial work. It covers only the bond between the overlay and the surface under it. A second Texas crew uses nearly the same wording. Its terms run about seven years on homes and a year and a half on commercial work, on the same bond.
One Tennessee crew says its work is warrantied against flaking for about 24 months. Another Tennessee firm shows a badge for a one-year limited warranty, and its concrete page adds a one-year warranty on crack fill.
An overlay can fail in more than one way. It can lose its bond, flake at the surface, crack, wear through, or change color. A term that names the bond alone leaves flaking and wear with you, and a term that names only flaking leaves the bond with you. Ask about the split between homes and businesses too. Under the first Texas terms above, the same overlay gets a term five times longer at a house than at a shop. The page doesn’t say why.
Ask: “Which failures does the warranty on my overlay name? And which term fits my building, home or commercial?”
2. Crack exclusions and the slab underneath
Concrete cracks, and an overlay follows the slab it sits on. A moving crack in the slab below will come up through any overlay, so leaving it out is fair. Ours leaves out slab cracks and movement, and even our own crack repairs, for that reason. The Missouri firm above lists just one exclusion: cracks that come back.
The firms that make the products write the same idea more broadly. One maker’s warranty on its stampable overlay leaves out the state of the slab below, or any movement in it. Another maker’s warranty on its concrete restoration products leaves out cracks from structural movement. That means the building itself shifting. One Oklahoma concrete firm turns the idea around. It offers to seal random structural cracks 1/8 inch or wider for a set term.
Watch the spot where a slab crack meets an overlay that let go, because that’s where the blame gets passed around. Some crews blame overlay delamination, the overlay peeling off in a sheet, on the base slab. Make them show you which one you have.
A reflective crack and a debond can look alike from standing height, but they’re not the same failure. A reflective crack starts in the slab underneath. It’s a joint or a moving crack that the overlay was laid across. It shows as a line that follows the old crack, and the overlay on both sides stays tight to the slab. A debond is the overlay letting go of the slab. It usually happens because the crew ground the surface to the wrong profile, left it dirty, or skipped the primer. It sounds hollow when you tap it with a hammer or drag a chain across it. It often cracks or curls at the edge of the loose area. A crack exclusion is fair for the first failure. It’s not a fair answer to the second one. A hammer tap tells the two apart in minutes, with no lab and no special tools.
Prep is the part the installer controls. Before an overlay goes down, we grind the slab to CSP 3 to 5. CSP is the ICRI concrete surface profile scale, and a higher number means a rougher surface for the overlay to grip. We also look at what kind of crack we have before we suggest an overlay at all. When a tap test isn’t enough, an ASTM C1583 pull-off test can settle a bond question.
Ask: “If my overlay cracks, will you tap the area for hollow spots before you call it a slab crack? And which cracks will you fix before you pour?”
Does the moisture exclusion name a test?
Clause 3. Moisture coming up through a slab can push an overlay off it, and a fair overlay term leaves it out. Ours does. The stampable overlay maker above leaves out moisture rising from the slab. It also leaves out efflorescence, the white powder that salts leave behind as water dries out of concrete. The maker of the restoration products leaves out subfloor moisture and water damage. Neither paper names a test or a number.
That’s normal for a product maker, which never sees your slab, but it matters more when an installer uses the same words and skips the test. Moisture is one of the few causes you can measure before the work starts. ASTM F1869, the calcium chloride test, measures how much vapor leaves the surface in 24 hours. ASTM F2170 uses a probe to measure relative humidity inside the slab. We check every slab. We test when the check shows a warning sign, like dampness, white mineral residue, or a past coating failure, or when you ask. When we test, we look for under 3 lbs on the first test and under 75% on the second. A slab that reads high gets a vapor treatment before the overlay goes down. Our moisture testing guide explains both tests.
Ask: “What moisture test will you run if my slab shows a warning sign? What number does the warranty on my floor use, and will you write the result on my paperwork?”
What do “normal conditions” and “improper use” mean?
Clause 4. One Texas concrete firm puts out more than most. Its warranty on resurfacing runs about five years on materials and workmanship, and it says that most often covers delamination, cracks, and early wear under normal conditions. The same page leaves out freeze-thaw damage, chemical spills, and improper maintenance. One Mississippi concrete firm leaves out damage from improper use.
Anyone can see freeze-thaw damage or a chemical spill and name it. Normal is harder. Nobody can test for “normal conditions,” “improper maintenance,” or “improper use” unless the paper says what normal is. With no care plan and no stated use, a crew can call any failure improper after the fact. Ours leaves out use beyond what we quoted the floor for. So ask any crew, us included, to write down on the estimate how the floor will be used. Then both sides can read it before anything goes wrong.
A clause nobody can test for is a way out
If nobody can test for a cause, a crew can blame it for any failure. You’d have no way to prove it wrong. Before you sign, ask which test and which number would prove the cause they left out. Then ask who pays for that test.
Ask: “What counts as normal use and proper care for my overlay, and which page of my paperwork says so?”
Does skipping a reseal void the warranty on your overlay?
Clause 5 is the one most specific to overlays. Most decorative overlays carry a sealer. Sealers wear. Resealing is real upkeep, and a fair term can require it. The Missouri firm above uses a solvent-based clear acrylic sealer and suggests a new coat about every two years.
In Texas, the first overlay crew above says you need a reseal about three years after the work. The client pays for it. The second sets about the same schedule, also paid by the client. Neither page says what happens to your coverage if a reseal comes late.
The stampable overlay maker goes further. Its system needs a fresh topcoat for upkeep about every three to five years. Its own inspector sets the dates, or a licensed contractor, or a design pro. It wants an inspection about a year after the install, then about every two years after that. The owner has to keep a written record. And the coverage ends if the materials aren’t kept up the right way.
A reseal schedule is fair when you can see it, afford it, and prove you kept it. An acrylic sealer on an overlay takes the traffic, the sun, and the cleaning. It wears thin long before the overlay does. Renewing it protects the color and the surface underneath. The trouble is a schedule that shows up only after a claim. Maybe the dates live in a paper nobody handed you. Maybe the timing depends on someone else’s judgment, or the proof has to be an inspection log you didn’t know to keep. Then a missed reseal becomes a way to deny a bond failure that has nothing to do with the sealer. A fair version gives you the dates at handover. It names the product, prices the visit, and limits a missed reseal to the wear it caused. Get that page before the final payment, and keep it with your receipts.
Ask: “When is my first reseal due, and what will it cost? Does a late reseal void the whole floor, or only the worn area?”
When is a color difference a defect?
Clause 6. Cement-based overlays vary in color. Ours leaves out color, color match, and how a finish compares to a sample. Concrete and cement finishes vary by nature. The maker of the restoration products leaves out color, shade, and texture that differ from samples. It also leaves out the white powder and shading that come with any cement-based product. The stampable overlay maker leaves out loss of gloss, fading, and cleaning.
Those are fair as far as they go. The risk is a firm that stretches a color exclusion to cover a real defect that just shows up as color. Think of a dark patch over a hollow spot. Or a blotch where one batch was mixed wrong, or a white haze from sealer rolled over a damp surface. “Natural variation” shouldn’t be the answer to a problem you can find with a hammer tap. A sample board or a small test patch on your own slab gives both sides something to compare.
Ask: “If one patch of my overlay looks off, how will you tell if it’s normal or a flaw under it?”
Who decides a claim on your overlay?
Clause 7. One maker’s warranty on its moisture-control system fixes only the areas the maker itself says were hit. The stampable overlay maker picks between new materials and a refund, at its sole discretion. After you tell it about a problem, it also keeps the right to come look and choose the fix.
Every warranty on a floor needs someone to inspect a claim. That part’s fine. The fair version puts the answer in writing, with a reason, inside a set number of days. Ours commits to a written answer after we look. It says whether we see it as a workmanship issue and what we plan to do about it.
Ask: “Who decides my claim, and how many days do you have to answer? Will a denial come in writing with the reason?”
Is labor covered, and does anyone cover the installation?
Clause 8. Product makers sell material, so they write terms for the material. One microtopping maker’s data sheet says it won’t pay for labor at all. The stampable overlay maker won’t pay labor costs either. Its exclusions even name a bad install. The maker of the restoration products leaves out poor prep of the slab below, too.
That’s fair for a company that never saw your floor. The trap is a crew that hands you that paper as the only written coverage. Grinding to the wrong profile, skipping the primer, or adding too much water to the mix are the usual reasons an overlay lets go. Under those papers, nobody pays to fix them. Material is the cheap part of an overlay repair. The crew is the costly part:
- grinding out the failed area past the loose edge
- priming the slab again
- placing and texturing new overlay
- resealing the repair so it blends in
Ask: “Which paper covers the prep and the install on my overlay? For how many years, and does it include labor?”
How long do you have to report a problem?
Clause 9. The maker of the restoration products wants a written claim within about 15 calendar days of when you find the defect. The stampable overlay maker allows about 90 days. File late, and you give up every claim. A hairline debond grows slowly. A short clock can run out before you know there’s a thing to report.
Both papers also say what happens if someone fixes the floor first. The restoration product maker wants to see the claim before any repair starts. That rule is fair, and ours has a version of it. If someone else repairs the floor before we look, we don’t cover it. The one exception is an emergency fix that stops more damage. A rule with no exception and no deadline to answer lets a slow crew run out your clock.
Ask: “How many days do I have to report in writing, and how many days do you have to come look?”
Can a denied claim cost you money?
Clause 10. Three costs can land on the owner in the maker terms we read:
- Inspection costs. Under one maker’s terms, the owner pays the maker’s related costs if the claim turns out not to be valid.
- Lab testing. One moisture-control maker has the building owner pay for the first round of testing. The maker pays the lab back if the lab finds its product at fault.
- The full bill first. The same moisture-control terms don’t take effect until the bills are paid in full.
Paying your bill before coverage starts is normal. A cost on a denied claim is different when the same firm decides the claim. Put a price on reporting, and people stop reporting real defects.
Ask: “Is there any fee to file a claim on my overlay? Who pays for testing if you say no?”
What rights does the fine print ask you to give up?
Clause 11. The stampable overlay maker sends disputes to arbitration in California. Arbitration is a private hearing in place of a court. Both sides give up any right to a jury. The moisture-control maker places any lawsuit in Arizona. From central Oklahoma, both are more than 800 miles away. Have a lawyer read a clause like that before you count on the paper it sits in.
Ask: “Which state’s law governs the terms for my floor, and where is a dispute heard? Does it waive a jury trial?”
Numbers with no written terms
4 listings promised coverage with no term at all. One Mississippi firm offers reliable coverage for commercial resurfacing, with no term stated. One Missouri firm says it offers a strong warranty on all of its work, and stops there.
Others give a number with no terms behind it. One Arkansas concrete firm advertises a 3-year warranty on all its projects. We found no exclusions published anywhere we looked. One Tennessee refinishing firm promises 3 years on all its refinishing work. A second Tennessee firm offers one year at the least, and longer depending on the system. The Mississippi firm from clause 4 says its real terms come in the service agreement. You see them only after you’ve already signed on.
One Oklahoma firm takes the opposite line. Its published policy has no fixed term. Its view is that material or workmanship problems usually show up within weeks, not years. The same page says your coverage is what both sides agree to in writing in the contract. On that point we agree.
Ask for the paper before you sign
We checked 30 contractor listings. 12 published no warranty terms for us to find, and 4 more promised coverage with no term. Ask to read the real paper before you sign, not after. A number with no terms tells you nothing about what the firm will fix.
How can you tell if an overlay contractor will stand behind the work?
Read their past, not only their paper. In 2026 we retested a cement overlay in Oklahoma with a clear coat on top. The clear coat had cracked and slab moisture was named as the cause, but the overlay itself was sound. Our ASTM F1869 retest read under 3.5 lbs, so at worst the slab sat half a pound over the 3-lb line we look for. Our epoxy floor guide walks through how a moisture test settles that kind of question. A short term from people who come back for the repair is worth more than a long one from people who fight every claim.
Three questions tell you more than the length of the term. First, ask for a reference whose overlay had a problem, and how the company handled it. Anyone who has laid overlays for more than a few seasons has had a callback. A contractor who claims otherwise is new or isn’t being straight. Second, ask what they check before they pour. That means moisture with ASTM F1869 or ASTM F2170, the surface profile after grinding, and which cracks and joints get marked and carried through the overlay. Those checks are what make a crack or moisture exclusion fair later. Third, ask what they’d do if part of your overlay sounded hollow in year two. Listen for whether the answer starts with a visit to look at it or with a list of exclusions. The first answer is the one to get in writing.
The same review for other floors
We ran the same search for the other floors we install, across the same 6 states. Each guide describes real, dated terms:
We publish a plain-English summary of our own workmanship warranty, with a list of what it doesn’t cover. That list names moisture coming up through the slab, slab cracks and movement, and color and matching. It also names repairs by someone else before we get a chance to look, unless it was an emergency. On our concrete overlay service, we check every slab. We test for moisture when the check shows a warning sign, and we grind to CSP 3 to 5 before an overlay goes down. When you’re ready to compare real numbers, get your price now.
